Grade 6Electrostatics
Two identical small balls each carrying like charges but in different amounts are suspended from two identical threads from a point.the angle between the threads at equilibrium is 74 degrees and is 60 degrees when immersed in a liquid. Find the relative permittivity of the liquid (neglect buoyancy forces).
